Mounting Considerations
CAUTION
Do not install or store the sensor near strong magnets, including
speakers. A strong magnetic field can damage the sensor.
For best performance, observe these considerations when
selecting a mounting location.
• The sensor should not be mounted near known ferrous metal
objects such as a toolbox or compass.
• The sensor is not a GPS device and is not required to have a
clear view of the sky.
• A handheld compass should be used to test for magnetic
interference in the area where the sensor is to be mounted.
If the needle on the handheld compass moves when you hold
it where you intend to mount the sensor, magnetic
interference is present. You must choose another location
and test again.
• The sensor should be mounted horizontally on a rigid surface
for best performance.
• The sensor should be mounted with the cable facing toward
the front of the boat for best performance.
NOTE: You can set the heading alignment automatically if a
GPS source is connected to the NMEA 2000 network. If you
are not using a compatible Garmin chartplotter, the boat must
be able to reach a cruising speed of at least 6.4 km/h (4
mph). You can set or fine-tune the heading alignment using
Fine Heading Alignment with a compatible Garmin
chartplotter. If these options are not available, you must align
the heading by adjusting the sensor installation manually to
point the cable toward the front of the boat, parallel to the
keel.
• Mounting screws are provided with the sensor. If you use
mounting hardware other than the provided screws, the
hardware must be made of quality stainless or brass material
to avoid magnetic interference with the sensor.
NOTE: Test all mounting hardware with a handheld compass
to make sure no magnetic fields are present in the hardware.

• Do not use excessive force when installing mounting screws.
Use only the amount of force needed to keep the sensor in
place.
• Apply force evenly between the mounting screws.
NMEA 2000 Connection Considerations
• This sensor connects to an existing NMEA 2000 network on
your boat.
• If the included NMEA 2000 drop cable is not long enough to
reach your NMEA 2000 network, a drop cable of up to 6 m
(20 ft.) can be used, according to the NMEA 2000 guidelines.

Calibration
After installation is complete, you must calibrate the heading
sensor for best results. Depending on the types of devices
connected to the NMEA 2000 network, you can calibrate the
sensor using either a menu-based method or a basic method.
When you connect the sensor to the same NMEA 2000 network
as a compatible Garmin chartplotter, you are prompted to begin
menu-based calibration when the chartplotter detects the new
sensor (Performing Menu-Based Calibration, page 2). Go to
www.garmin.com for a list of compatible chartplotters.
NOTE: A software update available in mid-2017 enables you to
perform menu-based calibration using a compatible chartplotter.
If your chartplotter has software that predates this update, you
must perform basic calibration.
If you connect the sensor to a NMEA 2000 network without a
compatible Garmin chartplotter, you must perform basic
calibration instead of menu-based calibration (Performing Basic
Calibration, page 2).
Performing Menu-Based Calibration
Before you can perform menu-based calibration, you must
connect the sensor to the same NMEA 2000 network as a
compatible Garmin chartplotter.
If the sensor has not been calibrated successfully, a message
appears each time you turn on a compatible Garmin chartplotter.
1 From the sensor calibration screen, select Compass Cal..
TIP: You can open the calibration page at any time by
selecting the device from Menu > Settings >
Communications > NMEA 2000 Devices.
2 Select Begin.
2
3 Follow the on-screen instructions until the compass
calibration is complete, taking care to keep the boat as
steady and level as possible.
The boat should not list during calibration.
If possible, you can turn the vessel in place by engaging two
engines in opposite directions.
When the compass calibration is complete, a value appears
near the Compass Cal. setting. A value near 100 indicates
the sensor was installed in a perfect magnetic environment
and calibrated correctly. If the heading performance is
unacceptable, and the value is closer to 0 than it is to 100,
you might need to relocate the sensor and calibrate the
compass again.
Select
Auto Heading Alignment.
4
NOTE: Auto Heading Alignment is available only if there is a
GPS source connected to the NMEA 2000 network. If you do
not have a GPS source connected, you must perform the
Fine Heading Alignment instead (Adjusting the Fine Heading
Alignment, page 2).
5 Select Begin.
6 Follow the on-screen instructions until the alignment is
complete.
Adjusting the Fine Heading Alignment
If you do not have a GPS source connected to the NMEA 2000
network, Auto Heading Alignment is not available as part of
menu-based calibration, and you must adjust the Fine Heading
Alignment instead.
You can adjust the Fine Heading Alignment in conjunction with
Auto Heading Alignment to fine-tune the heading output
(optional).
1 From the sensor calibration screen, select Fine Heading
Alignment.
2 Using a landmark or a known good compass, determine the
heading of your boat.
3 Adjust the heading until it matches your measurement.
4 Select Done.
Performing Basic Calibration
If you connect the sensor to a NMEA 2000 network without a
compatible Garmin chartplotter, you must perform basic
calibration instead of menu-based calibration.
You must be able to view heading data from the sensor on a
connected chartplotter or marine display before you can perform
basic calibration. If you cannot view heading data on your
connected display, check the NMEA 2000 network and power
connections.
All other sources of heading data that are not based on GPS
must be removed from the NMEA 2000 network while
performing basic calibration.
When performing basic calibration, you first calibrate the
compass and then align the heading in one continuous
procedure. If you installed the sensor with the cable pointing
toward the bow, parallel to the keel, it may not be necessary to
align the heading.
NOTE: If you choose to align the heading, you must connect a
GPS source to the NMEA 2000 network. The boat must be able
to reach a cruising speed of at least 6.4 km/h (4 mph) to perform
the heading alignment.
1 Drive the boat to a location with calm, open water.
2 Set the display to view heading data from the connected
sensor.
3 Disconnect the sensor from the NMEA 2000 network or turn
off the power to the NMEA 2000 network.
4 Wait while the boat becomes level and stationary.
5 Turn on power to the sensor, and wait until the heading data
appears on the display À.
10 When it is safe, straighten the boat and drive in a straight line
Æ at cruising speed (must be at least 6.4 km/h (4 mph)) until
the heading data appears Ç.
When the heading appears, the compass has been
calibrated, and the heading has been aligned on the sensor.
11 Test the results of the calibration, and repeat this procedure if
necessary.
Restoring Factory Default Settings
6 Within three minutes, complete two full, slow, tight circles Á,
taking care to keep the boat as steady and level as possible.
The boat should not list during calibration.
If possible, you can turn the vessel in place by engaging two
engines in opposite directions.
When the sensor is prepared to calibrate the compass, the
heading data disappears from the display Â.
You may receive an error message that the heading was lost.
You can ignore this message.
7 Continue turning in the same direction at the same speed Ã
for approximately 1 1/2 rotations until the heading data
appears Ä.
If you relocate the sensor or do not believe the calibration was
successful, you can delete all calibration information from the
sensor, and restore its factory default settings. After restoring
the factory default settings, you must configure the sensor
before you can use it with your system.
1 Select Settings > Communications > NMEA 2000 Devices
> Device List.
2 Select the name of the sensor.
3 Select Review > Factory Defaults > Yes.

When the heading data appears, the compass has been
calibrated successfully, and you can align the heading
(optional).
8 Select an option.
• If you want to align the heading to match the front of the
boat, proceed to the next step.
• If you installed the sensor with cable pointing toward the
bow, parallel to the keel, and do not want to align the
heading, stop turning and wait, keeping the boat
stationary. Over the next two minutes the heading data
should disappear and then reappear. When the heading
data reappears, the compass should be calibrated and no
heading offset should be applied.
NOTE: If an unwanted heading offset is applied, you must
disconnect all GPS sources from the NMEA 2000 network,
and repeat the calibration. If the only available heading
display is also a GPS source, you must repeat the
calibration, and disconnect the sensor after step 7.
9 Continue turning in the same direction at the same speed for
approximately ten seconds, until the heading data disappears
from the display Å.
